The invention relates to a manufacturing method of a straight thrust rod and the straight thrust rod, and relates to the technical field of automobile spare and accessory parts, the thrust rod comprises a plurality of prefabricated parts, the prefabricated parts are assembled, each prefabricated part comprises a hollow straight rod and two spherical hinge seats, a first welding surface is formed at each of two ends of the straight rod. The spherical hinge base comprises a base body and a hollow welding section, one end of the welding section is connected with the base body, and the end face ofthe other end is a second welding face; the manufacturing method comprises the following steps that the second welding faces of the two welding sections are attached to the first welding faces of thetwo ends of the straight rod correspondingly, so that the welding sections and the straight rod are coaxial; the straight rod and the spherical hinge base relatively rotate around the central axis ofthe straight rod and the central axis of the spherical hinge base, and first preset pressure is applied, so that the first welding face and the second welding face extrude each other and are welded together through friction; and a second preset pressure is applied, so that the first welding surface and the second welding surface extrude each other until flanging structures are formed on the innersides and the outer sides of the first welding surface and the second welding surface to form the thrust rod.
Description
technical field [0001] The application relates to the technical field of auto parts, in particular to a method for manufacturing a straight thrust rod and the straight thrust rod. Background technique [0002] The thrust rod is one of the key components of the balance suspension and air suspension of the truck. It is divided into a straight thrust rod (or called I-shaped thrust rod) and a V-shaped thrust rod. , and play a vital role in mitigating shocks. Generally, a thrust rod is composed of a sleeve, a ball joint and a ball joint. [0003] In the related art, the aluminum alloy split type straight thrust rod is composed of a bushing, a ball head and a ball hinge. Ball heads are installed at both ends of the bushing respectively, and the ball hinge is installed in the through hole of the ball head; the ball hinge of the ball head is installed The combination of the seat and the bellows section is a combination of an ellipse and a circular arc, which improves the bearing c...
